如何在带有FlaUI的Visual Studio2019中使用视图而不是窗口进行测试？

using FlaUI.Core;
using FlaUI.UIA3;

...

[TestClass]
public class MyTests
{
    private Application _app;
    private AutomationBase _automation;

    [TestInitialize]
    public void Initialize()
    {
        _automation = new UIA3Automation();
        _app = Application.AttachOrLaunch(new ProcessStartInfo("path/to/your/application.exe"));
    }

    [TestMethod]
    public void MyTest()
    {
        var mainWindow = _app.GetMainWindow(_automation);
        // 使用视图进行测试，例如查找和操作按钮
        var button = mainWindow.FindFirstDescendant(cf => cf.ByAutomationId("buttonId"));
        button.Click();
        // 进行其他测试操作...
    }

    [TestCleanup]
    public void Cleanup()
    {
        _app.Close();
        _automation.Dispose();
    }
}
